There was a problem, but was rolled back pretty quickly


At 5:59 AM UTC, June 03 2020, the Salesforce Technology team became aware of a service disruption, affecting customers ability to access force.com domain. The Salesforce Technology team identified a recent Domain Name Server (DNS) configuration change to be the likely cause of the issue and successfully rolled back the DNS change across the force.com domain, which brought most of the customers out of impact.

While the Salesforce Technology team continued to validate the normalised state of services, additional issues were reported by customers across a few other domains. As a best and immediate path to resolution, the technology team initiated a full roll back of the DNS Configuration change across all the domains in production and Test. As of 8:39 AM UTC, June 03, the rollback has been successfully completed across the Production domains. The services have been validated and confirmed to be out of impact.

Should the Customers still continue to experience issues while accessing the Salesforce services, please remain advised to clear the browser cache on individual machines. Should clearing of the browser cache not resolve the issues, the customers are advised to clear the DNS cache on their individual machines.

We thank you for the continued business support and patience. Posted 4:48 pm AEST, Jun 03 · Last updated 7:14 pm AEST, Jun 03
